I just had the oil changed at my mechanic I trust (been going to him for over 15 years). I changed to Mobil 1 5w20 with OEM Honda Filtech Oil filter. I dont know if I am paying extra attention to the car, but the car seems to run a lot smoother. Any thoughts any one? My car currently has 36K Miles on it, I bought it new and this was the first time I am going to Synthetic oil.

 

Mobil 1 is a very good choise..........but as good as it is,, i would advice to still replace oil and filter every 3k to 3.5 k miles
